Thank you for using two-step verification to protect your Apple ID and the data you store with iCloud.

This is a reminder that starting tomorrow, app-specific passwords will be required to access your iCloud data using third party apps such as Microsoft Outlook, Mozilla Thunderbird, or other mail, contacts, and calendar apps.

If you are currently signed in to a third party app using your primary Apple ID password, you will be signed out automatically when this change takes effect. You will need to generate an app-specific password and sign in again.
